mltype VS layout

https://github.com/jankrepl/mltype is something like this. It is tuned for programmers though. And the quality of generated text might vary a lot. But it gives reasonable char sequences.

This script does require a package called mltype

The layout is a simulate annealing optimized layout which I've added to stevep99's Keyboard Layout Analysis Tool it's available on the sa-tidy branch for now. I liked NotGate’s SFB minimized layout but wanted to expand and add more finger roll and make sure it's optimized for English as well as C/C++/Rust and Python.

It is commonly used on a thumb key (Right-alt on tradtional keyboards) to repeat an alphanumeric key to avoid double tapping with the same finger, making it a smooth motion instead and helping in the same vain as reducing same finger bigrams. For example typing "hello" you would instead do hel{rAlt}o. See also the bottom of https://notgate.github.io/layout/

IRST

Looks okay. Right ring is a little questionable (try typing "you" on it), and there's also a layout with 0.473% SFBs.

Thanks for the reply! Interesting how you skipped colemak, I'd be curious to hear your thoughts on plain colemak if you decide to give it a go. I might do the same with colemak-dh or IRST for that matter.

Looks like NotGate's SFB Minimized Layout (https://notgate.github.io/layout/)
